Abstract

The invention discloses a seawater desalination, resource comprehensive utilization and zero discharge processing system. The system comprises an ultrafiltration (UF) system, a seawater reverse osmosis (SWRO) system, a deionized water processing system, namely an UPW system, a mechanical compression system capable of preventing scaling and a salt manufacturing and salt chemical engineering system, wherein the UF system is used for generating pure seawater; the SWRO system is used for generating desalted water and concentrated seawater; the concentrated seawater can be produced into calcium sulfate, sodium chloride, potassium chloride, magnesium sulfate, bromine, magnesium chloride and steam condensed water by virtue of the mechanical compression system and the salt manufacturing and salt chemical engineering system; and the steam condensed water and a part of desalted water flow into the UPW system to generate deionized water. According to the processing system, the relevant projects of seawater desalination, energy source utilization, industrial salt manufacturing and salt chemical engineering are organically combined, so that reasonable allocation and utilization of resources are realized, and the aims of energy conservation, emission reduction, circular economy and zero discharge are fulfilled.

Description

technical field [0001] The invention relates to comprehensive utilization of seawater, in particular to a treatment system for desalination of seawater, comprehensive utilization of resources and zero discharge. Background technique [0002] The world is facing water resource problems, the security of fresh water supply is facing severe challenges, water resources are becoming increasingly scarce, and the water environment is deteriorating. It is of great strategic significance for my country to accelerate the comprehensive utilization of seawater and resources, reduce operating costs, and develop high-tech and industrialization of seawater utilization. [0003] Seawater desalination methods mainly include distillation, electrodialysis and reverse osmosis, and the recovery rate is generally 40-45%. The low recovery rate and high energy consumption have resulted in high cost pressure and limited economic development. [0004] The current SWRO concentrated seawater is mainly...
